In addition to carry forward guns from MW2, Call of Duty: Modern Warfare 3 will have its own set of unique weapons that players can unlock, level up, and complete mastery camo challenges for.
MW3 introduces 37 new weapons to the game and you can unlock these by ranking up in Multiplayer or Zombies. The progression tree contains all the weapon unlock levels, and I've listed them below.

Keep in mind that pre-unlocked weapons become usable only after you unlock the Gunsmith at level four; only then you will be able to customize your loadout and edit the attachments on guns. You'll also notice that several weapons can be acquired via Armory Unlock, which becomes accessible once you reach level 25. From the available list, select the weapon of choice and unlock it by completing three daily challenges. This makes acquiring new weapons slow compared to getting them directly by rank progression.
